Got the TBI installed, but have ignition questions
Got the Affordable Fuel Injection kit installed over the weekend, everything went great. Jeep starts and runs down the road fine, but seems to miss at idle. It did this with the carb setup too, I just always kinda blamed the carb. The ECM doesn't have any codes, and check engine light stays off, so that's why I suspect ignition. I haven't upgraded the ignition, all stock stuff. It does have new plugs, wires, cap, and rotor though. But while idling, the engine shakes, and is generally not smooth. Checked for vacuum leaks, timing, etc. I'm going to do the team rush upgrade on the cap, rotor, and wires, and use an e-coil. I think this will help alot, but I'd like to have a multispark cdi unit as well. I'm not sure if that will work though with the fuel injection setup? The way I understand it, the ECM controls the spark now, so is it multispark already? If not, how would I wire in a multispark cdi unit?
